CVE-2020-27858

This vulnerability allows remote attackers to disclose sensitive information on affected installations of CA Arcserve D2D 16.5. Authentication is not required to exploit this vulnerability. The specific flaw exists within the getNews method. Due to the improper restriction of XML External Entity (XXE) references, a specially-crafted document specifying a URI causes the XML parser to access the URI and embed the contents back into the XML document for further processing. An attacker can leverage this vulnerability to disclose information in the context of SYSTEM. Was ZDI-CAN-11103.

Esta vulnerabilidad permite a atacantes remotos divulgar información confidencial sobre las instalaciones afectadas de CA Arcserve D2D versión 16.5. No es requerida una autenticación para explotar esta vulnerabilidad. El fallo específico se presenta dentro del método getNews. Debido a una restricción inapropiada de las referencias de XML External Entity (XXE), un documento especialmente diseñado que especifica un URI causa que el analizador XML acceda al URI e inserte el contenido en el documento XML para su posterior procesamiento. Un atacante puede aprovechar esta vulnerabilidad para revelar información en el contexto de SYSTEM. Fue ZDI-CAN-11103
